The SX1000 features 0RPM upto 300W and outputs between 20~25dB(A) noise upto 700W. The stock fan produces noticable motor noise which is audible alongside the fan noise between 300~700W range. Noise output substantially increases above 700W with max output of 45dB(A) at 1000W. Noise testing data sourced from Cybenetics.


The SilverStone SX1000 (v1.1) uses 120x15mm Globe Fan at 12v, 0.45amp (model: B1201512HB) with 2-PIN mini fan header. Mainstream fans from Noctua, Thermalright, Scythe, ARCTIC etc will not spin up when paired with the SilverStone SX1000 due to lower ampage. This means fan replacement for the SilverStone SX1000 will be difficult as 120x15mm fans using 0.45amp are very uncommon and will likely be lower quality than the included fan and therefore pointless.
